WIRE-1100M.

Specification of Letters Patent.

Application filed September 2, 1919. Serial No. 321,115.

To all whom it may concern:

Be it known that'I, HARRY DENBY, a 'citizen of the United States and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new 7 and useful Improvements in Wire-Looms,

' situations.

of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide improved mechanism for continuously manufacturing Woven wire fabrics, such as are employed for the screen used for protection from thieves in banks and othe The woven wire fabric is composed of previously prepared wires of equal length which are crimped at intervals determined by the required size and mesh.

The wires are fed alternately from the adjacent sides of an annular frame thus producing a fabric constructed on the bias or with the strands running diagonally to the direction of greater length of the fabric.

In this application particular reference is made to means for spreading apart the extremities'of the alternate wires on each side of the fabric to permit the insertion of ad ditional wires .and to provide means for guiding the inserted wires into the machine; the guiding means servmg also as instru- 'mentalities for transferring the inserted wires to their proper positions in the completed fabric.

The invention also includes positively acting mechanism for pulling the fabrics forward as fast as manufactured in exact relation to the size of the mesh required thus permitting wire fabrics of different size of mesh to be constructed on the same machine.

The invention includes a support for the fabric, supporting and guiding means for the fabric propelling device, and adjusting means for the propelling means, and also for the mechanism which controls the transfer of the inserted wires to their final position in the fabric.

It includes also the method of constructing a compact and efficient machine in which the movements are powerful and positive in action and ca able of adjustment to produce fabrics of different sizes of mesh.

The invention is illustrated in the accompanying drawings hereinafter more fully described and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a plan of the device; Fig. 2 is a transverse section v showing the wire placing fingers; 111g. 3 1s a side elevation; Fig. 3 is a perspective of one of the crank arms that operate the lower toothed bar; Fig. 4-; is an enlarged side elevation showing the method of operating the toothed bars which spread the extremities of the wires to permit the ntroductions of the inserted wires; Fig. 5 1s a plan of the angular connection between the toothed bars; Fig. 6 is a longitudinal section showing the fabric propelling de- Patented Aug. 31, 1920.

vice; Fig. 7 is a transverse section thereof;

Fig. 8 is a plan of the gearing connecting the operating shafts for the spreading bars; Fig. 9 is a side elevation thereof.

In these views A is an angular frame having the corner angle bar A and end-bars A A and connecting members'A A and A, and diagonal cross bar A.

The fabric, as fast as constructed, lies upon a horizontal metal plate B, and passes underneath the metal bar C to. which the propelling mechanism is attached.

The fabric W passes centrally between i the adjacent sides of the angle, and the inserted wires, W, W are added continuously through the sides at the corner of the angle as shown in Fig. 1.

To raise and lower the extremities of adjacent wires in the fabric already constructed to permit the introduction of the inserted wires between them, opposed bars D,

D, are moved toward and away from each other and are provided with spaced teeth D D which are alternately arranged on the opposed bars and engage the projecting ends of alternate wires.

As these bars approach each other the ad jacent projecting wire ends are raised and lowered by the teeth D D so as to spread them vertically apart to permit the insertion of additional wires W, W

This action is illustrated in Fig. 2 where the bars are shown closed and the end wires spread apart to receive the inserted wire WV which rests upon a series of fingers E, E, mounted upon the shafts F parallel with the bars D, D, in the machine.

When the lower bar raises the fingers and the shaft F is raised to the position shown in solid lines and guides the wire W into the open spa-ce'between the wires \V, the shaft F is then rotated by means of a lever F and the fingers l) draw the wire W into its position at X in the completed fabrics as shown in dotted linesat the top of the figure.

\Vheii the bars separate the fingers fall to the position shown in dottedlines at the lower side of the figure.

The amount of movement of the fingers is limited by a screw G mounted in a bracket G on the lower bar and a stop H'limits the movement of the shaft F. Auxiliary arms I, I, are preferably attached to the upper and lower bars to separate adjacent ends of wires which are out of the vertical plane of the bars D, D, these are V shaped in section to receive the bars.

As soon as the insterted wires are in place the entire completed fabric is moved backward by means of the mechanism illustrated in Figs 7 and 6.

Here J is a combshaped bar having vertical slots J in its lower edge and inclined slots J? in its upper edge. This comb or rack moves in the longitudinal slot K between metal bars K on the table and the intersecting parts or angles of the meshes of the fabric are engaged by the sides of the vertical slots, thus pulling the fabric diagonally across the table. The act of pulling the fabric along the line of its longitudinal axes, and applying the drag to the intersecting points of the wires, prevents the wires from folding, because the intersections are held rigidly apart in their original spaced positions and the fabric cannot collapse.

Upon the cross bar C, is pivoted a swinging lever L to which a dog, M, is pivoted at the lower end and the link rod N at the upper end operated by the red O and lever O. The dog M, engages with the inclined slots in the upper edge of the comb and moves the comb and woven fabric backward with a regular intermittent movement, one space at a time, when the lever O is operated; thus making room for-the introduction of another set of wires.

A set screw P limits the movements of the swinging lever to adjust it to correspond with the width ofthe diagonal. of the mesh of the fabric constructed in the machine. A guard J 3 prevents the comb from rising.

The bars, D, D, are alike on both fronts of the machine and the bars on both fronts are operated simultaneously by means of shafts Q, and bevel gears Q, Q, positioned in the angle of the corner post of the frame.

The upper bars are connected together by means of the angle bar R, and are operated by cranks S, S, on the shafts Q and links S.

The lower bars are operated by cranks T, on the shafts Q, and Q, and links T and move in guides. A'leve'r T and the shafts through the agency of the chain T and the wheels T by means of which the amount of movement of the shaft is increased.
